In the past there have been problems with the Cygwin version of Python, e.g.

  http://www.ethereal.com/lists/ethereal-dev/200203/msg00416.html

These problems may not be relevant nowadays but I don't know if anyone
has tested modern versions of Cygwin's Python extensively. After
enabling "PYTHON=env python" in config.nmake on a system here (Cygwin
1.7.7 + Python 2.6.3 + Visual C++ 10) I was able to generate and compile
packet-ncp2222.c without any problems but that's just one environment of
many that we support, and that only tests a subset of the Python scripts
that we ship.
